scsi: qedf: Limit number of CQs
FCOE offloading failed with:
[qed_sp_fcoe_func_start:150(sp-0-3b:00.02)]Cannot satisfy CQ amount. CQs
requested 8, CQs available 6. Aborting function start
[qed_fcoe_start:821()]Failed to start fcoe
[__qedf_probe:3041]:6: Cannot start FCoE function.
The reason is a newly introduced check in the qed main part. This change
also provides the information about how many CQs are available, so we
simply limit the number of requested CQs..
Fixes: 3c5da9427802 ("qed: Share additional information with qedf")
